Centuri Holdings, Inc. (CTRI) stock intrinsic value fair value estimate & owner earnings analysis

Centuri Holdings builds, maintains and replaces the pipes and power lines that gas and electric utilities rely on. It operates through four segments — U.S. Gas, Canadian Operations, Union Electric and Non-Union Electric — working in 46 U.S. states and six Canadian provinces. The company became independently public in April 2024, when it was spun off from Southwest Gas Holdings; Southwest Gas remains a small customer today (about 3% of revenue), not a controlling owner. The business is built on long-term relationships: about 78% of revenue comes from multi-year master service agreements for recurring maintenance and replacement work rather than one-off construction jobs, and 79% of revenue is billed on a unit-price or time-and-materials basis rather than fixed price, which limits the risk of a project running over budget. Contracted and expected work on the books (backlog) totals roughly $5.9 billion, about twice a year's revenue, with 82% of that tied to the long-term agreements. That combination gives good near-term visibility into demand. Cash generation has been steadier than the reported accounting profit suggests. In fiscal 2022 and 2023, Centuri wrote off $177 million and then $214 million of goodwill from acquisitions made before it was spun off — these are the kind of write-downs that come from having paid more for a past deal than it turned out to be worth. Those charges produced large reported net losses in both years, but they were non-cash: the underlying cash the business throws off after real running costs (what we call owner earnings) stayed positive throughout, running between roughly $0.59 and $1.16 per share across fiscal 2022-2025, with fiscal 2025 the strongest year at about $1.06 per share as revenue grew 13% and the company kept paying down debt (long-term debt fell from about $1.1 billion at the end of fiscal 2023 to roughly $700 million now, cutting annual interest expense from $97 million to $78 million). We treat the write-downs as sunk cost from past deals rather than an ongoing expense, but the pattern itself — two straight years of material impairments — is a fair caution about how much value future bolt-on acquisitions (the company made a small one, the Connect acquisition, in November 2025) might destroy, and we've weighted that into the bear case rather than the earnings itself. The most recent reported quarter is a genuine yellow flag worth naming plainly: revenue grew about 33% year over year, but profit growth stalled and came in slightly below the prior year's quarter. Within the fast-growing Non-Union Electric segment, gross margin fell from 12.7% to 9.8% during fiscal 2025 as high-margin storm-restoration work (repairing electric infrastructure after major storms) shrank and was replaced by lower-margin recurring contract volume, including growth tied to data-center and distributed-power demand. That margin mix shift, not a falloff in demand, is the central risk to watch, and it shows up in both cases below. Two other factors shape the range of outcomes. First, customer concentration: the top ten customers generate about 48% of revenue and the top twenty about 65%, and while most relationships are long-standing, individual contracts can generally be reduced or ended on relatively short notice. Second, leverage: roughly $700 million of debt remains, which is the reason a downturn would hurt more than the base case implies — we've built that risk into the bear case directly rather than by discounting the whole business more heavily, since a heavier discount would understate what the business is worth if things go reasonably well. Owner earnings per share grew about 79% in fiscal 2025 versus fiscal 2024, but that's a rebound off a weak prior year (fiscal 2024 revenue had actually declined), not a repeatable growth rate, so none of the three cases below assumes anything close to it continuing. Bear case (about $13.81/share): starts near $0.80 per share, reflecting the margin pressure already visible in the most recent quarter, grows only about 2% a year as backlog converts but margin stays compressed, and drifts slightly lower in the back half of the ten-year window as customer concentration risk partly bites (a top-10 relationship shrinks or isn't renewed). After that, earnings power is assumed to simply persist at that lower level — the recurring, contracted nature of the work continues, but nothing further improves. Base case (about $23.51/share): starts around $0.90 per share — modestly above the four-year normalized level, reflecting real improvement (falling capital spending as a share of revenue, falling interest expense as debt is repaid) that isn't yet fully proven out. Growth runs about 9% a year for three years as the current backlog converts, slows to 6% for three years, then 4% for three years as growth normalizes toward the pace of ordinary utility infrastructure spending. Earnings power then holds at that level rather than being assumed to keep growing, because we found no specific evidence — no announced project, no disclosed multi-year program — to justify further growth past that point. Bull case (about $36.39/share): starts near fiscal 2025's actual level of about $1.00 per share, on the view that the recent improvement holds. Growth runs about 17% a year for three years as the data-center-adjacent electric demand and current backlog continue converting well, slowing to 10% and then 6% as the business matures, with the same flat continuation thereafter. The margin-of-safety price of about $14.00 per share applies a larger-than-usual discount to the base-case value (roughly 40%) because the public track record here is short — really only about two clean fiscal years since the spinoff — and because of the debt load and the margin question raised by the latest quarter. That price also assumes gross margin stops declining (holds at or above its fiscal 2025 level) for two consecutive quarters, as confirmation that the recent pressure in the Non-Union Electric segment isn't becoming a company-wide problem. What would make this wrong: if the margin pressure seen in the latest quarter spreads across segments rather than staying isolated to the mix shift away from storm work, or if growth from the current backlog doesn't convert to revenue as expected, the bear case is the more likely outcome. If instead margin recovers as storm work stabilizes and the data-center-related electric demand keeps compounding at its recent pace, results move toward the bull case.
